#1 - I AM POOR at math. I used to be OFF the chart right-brained, so badly, that when I was a substitute teacher in 4th/5th grades, I had to get the smartest kid to figure out the answer to the math problems - and I HAD THE ANSWERS IN THE teacher's book! I had no clue how they came by those answers. I'm not ashamed to admit it. I stuck to 1st/2nd/3rd grade whenever possible, LOL. So my sister (and my daughter) told me to try Sudoku for logic. It's helped. SOME. Not as much as I hoped, though. ;-D
